Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied…

Anthropologists created a computational model to predict the likelihood of animal extinctions based on the complex interaction of hunting and environmental change.

Quantum simulators are quantum systems that can be controlled exceptionally well. They can be used to indirectly learn something about other quantum systems, which cannot be experimented on so easily. Therefore, quantum simulators play an important rol…

What makes us human? According to neurobiologists it is our neocortex. This outer layer of the brain is rich in neurons and lets us do abstract thinking, create art, and speak complex languages. An international team has identified a new factor that mi…

New research suggests people who are scheduled for certain medical procedures should stop taking popular weight loss drugs in the days or weeks prior to avoid complications.

An enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis.

A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new vie…

Researchers have discovered a safer and more efficient technique for testing new drugs while they are in development.

Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.

Researchers are enhancing immunotherapy effects against malignant tumors by developing and validating patent-ending poly (lactic-co-glycolic acid), or PLGA, nanoparticles modified with adenosine triphosphate, or ATP.

Researchers say they have discovered that the protein puromycin-sensitive aminopeptidase (NPEPPS) plays a role in regulating response to platinum chemotherapy in patients with bladder cancer.
